A feather floating through the air has more kinetic energy because the rock is not in motion its on the ground the feather is moving in the air at a pretty fast rate of speed.
Answer:
Alpha-1
Explanation:
Adrenergic receptors are the integral proteins present in the postsynaptic plasma membranes. These receptors are activated when the neurotransmitter norepinephrine and the hormones norepinephrine and epinephrine bind to them. The alpha 1 adrenergic receptors are found in the smooth muscle fibers of blood vessels that serve the salivary glands, skin, and kidneys. These receptors are also found in the radial muscle of iris of the eye as well as in the sphincter muscles of the stomach and urinary bladder.
They exert excitatory effect and lead to contraction of smooth muscles of the blood vessels, dilation of pupil, and closure of sphincters of the bladder.
Carbon is both a waste product and an energy source in cellular respiration occurring with glucose molecules and forms the base element in the cellular respiratory cycles of glycolysis and the subsequent Kreb's cycle in which glucose is transformed into energy.
